Unlikely there'll be two separate large-scale gamemodes. I think the new mode will probably be close to Titan, with two opposing capital ships and command posts on the ground, which you have to capture in order to weaken and destroy the enemy Titan. Idk, this is all speculation at this point.

did none of you play battlefield 2142? Titan mode was the best battlefield mode, you had to capture silos and then they would target the enemy titan ship, if the other team held all the silos your titan would be hammered by the missiles, whoever owned all the silos knocked the other teams titan shields out first.

Then you'd use drop ships or APC with drop pods to board, you could also land the dropship or gunship on the cargo deck and take out enemies so teammates could board.

there were two small shafts on top that you could drop down to gain entry or two doors on the cargo deck.

onces inside you had to destroy some control panels to lower some door shields, then you were able to shoot the main reactor which would start a short countdown, you had a few seconds to escape and if you timed it right, you got a titan escape award, and you got to see the titan explode. you also had a parachute in 2142.
